HYDROCARBON-VAPORIZERT Specification of Letters Patent.

. Patented Dec. 10, 1912.

Application filed February 21, 1912. Serial No. 679,122.

To all whom "it may concern:

Be it known that I, HEnscnsL M. CoN NER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in HydrocarbomVa porizers; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to hydro carbon oil burners, and especiallyto burners of this nature which are adapted to generate hydrocarbon vapors from kerosene, although the present invention may be also utilized in burning gasolene or even hydrocarbons somewhat heavier than kerosene.

The object of the present invention is to provide a burner which will avoid the well known objections common to hydro-carbon burners heretofore proposed, and to produce at the same time, a burner which will be simple in construction, certain in action, and comparatively inexpensive to manufacture,

With these and other objects in view, the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and pointed out in the claims. I

Referring to the accompanying drawings forming a part of this specification in which like numerals designate like parts in all the views:F igure 1 is a longitudinal sectional view of a burner made in accordance with my invention; Fig. 2 is a detail sectional view on an enlarged scale of the vaporizing portions of my invention; and, Figs. 3, 4. 5

and 6 are detaiLviews of certain of the in dividual parts employed in the vaporizing apparatus. i

This invention in a sense, constitutes an improvement over the burner disclosed in my prior Patent No. 945,305 entitled .Vaporburners, and dated January 4, 1910.

Referring to the above drawings :1 indicates a portion of the frame of the burner, which is removably fitted to a hollow casting 2, provided with the nipples 3 and 4, into which are screw-threaded the pipes 5 and 6. The pipe 5 has screw-threaded on its outer end, the curved pipe 7 which may be slightly enlarged at its other end as at 8, to form an air mixing chamber 9. Attached tothe enlarged portion 8 of the pipe 7 is the particularly 18 entering the pipe 19, screw-threaded into the nipple 20, carried by said casting 14, and through which said passage ,18 passes, The ipe 19 carries the screwt-hreaded thimble 21 into which fits the en larged pipe 22, integral with the smaller pipe 23, extending through said perforated I smaller casing 11, as illustrated. The extreme end of-the pipe 23 screw-threads into the nozzle 24, fitting the partition 25, rigid with the member 8. i The said nozzle 24 also enters the airmixing chamber 9, as shown. The outer casing 10 provides a chamber or space 26 communicating with the pipe or passage 27 connected with the passage 28 in the casting 2.

30 indicates an opening in the chamber 9 through which air may be drawn, and as will be disclosed below, hydro-carbon "apor generated in the tube 22, passes through the nozzle 24, the chamber 9. where it is mixed with air; through the bent pipe 7, and pipe 5 into the casting 2, whence it is delivered through the pipes 31 and 32 to lamp mantles 33, only one of which is shown. An additional portion of the vapor delivered to the casting 2, passes through the passage 27 into the chamber 26. through the perforations 40 into the casing 11, where it is'ignited, and maintains the pipes 22 and 23 at a temperature sufficient to vaporize the oil.

I do not deem it necessary to describe more fully the above construction and its .operation, for the same is, or may be. substantially like the corresponding parts disclosed in my former patent above.

In the pipe 22, I provide a wire gauze tube i 35 closed at one end as by the plug 36 (see Fig. 5) and open at its other end, which is placed in register with the opening 37 through the nipple 21. I also wrap this gauze tube 35 with a plurality of layers of asbestos thread 38, and at one end, prefer ably the open end, I enlarge the wrappings 1 which rod an as at 39, so as to make a fairly tight fit with the interior of the tube 22. These wrappings are preferably in two layers along the main body of the tube 35, and are in three or more layers at the enlarged end 39, but I so adjust the 'wrappings as to allow a suffi cient porosity to permit oil vapors to. pass between the individual portions of the said wrappings, and to occupy the space bet-ween said wrappings 38 and the inner wall of the tube 22. Said pipe 22 and the parts con is disclosed in my former patent above, whilethe. said wrappings and tube 35 serve to prevent pulsations. inthe light, just. as efliciently as does my wrappings 27in the said patent. The oil vapor which passes through the 'wrappings 3S enters the tube 23, where it flows around and along the rod 45, which is wrapped with layers of asbestos 46, and

wrappin s occupy a considerable portion of the said tube 23, thus causing. the vapor to be formed into'a thin film. Said wrapping 46 is saturated with the oil vapors delivered thereto, and thus provides a uniform and constant supply of fuel for delivery to the burners. Accordingly, when said oil vapor is driven out of thetube 23 by the high heat to which the tube is sub- 'ected it asses throu h a foraminous or wire gauze'tube 47 closed at its outer end 55, and at lts other end, held in the metal tube 48 open atboth its ends, and screw-threaded I in the nozzle 24, as shown. The said tube 48 extends from the nozzle 24 into the tube 23, as shown, thereby leaving a pocket or space 49, which is closed at its bottom, and which is adapted to catch any condensed vapors 0r unvaporized particles of carbon, and prevent the same-from passing through the very fine orifice 50 with which the nozzle 24 is provided. I consider this construction involving the foraminous tube 47, metal tube 48, and pocket 49, as another important feature of my invention, for the said foraminous tube 47 effectually prevents any flarebacks, while the pocket 49 collects the larger unvaporized particles and prevents them from clogging the burner, and therefore, enables me to maintain a steady light. The said rod 45 is provided with projections 51 and 52 at each end, in order to hold the same centrally of the tube 23, and permit a ready.

evolution of vapors from the asbestos cover 46.

The operation of my vapor burner will be read ly understood from. the foregoing, but

may be briefly summarized as follows 2' The generation of vapor is started by the usual torch which may be applied to the tube 22, whereupon vapor will be emitted through the orifice 50, mixed wit-h air coming in through the passage 30, and the mixed air and vapor will pass through the pipes 7 and 5'into the casting 2, passage 27, into the chamber 26,and through the perforations 40 in the casing 11, whereupon the said mixed air and vapor will escape at the open end 12 of the casing 11, and become ignited.

The ignition of this-mixed air and vapor, will heat the tube 23, and of course, generate larger quantities of vapor, whereupon the mantles 33 will be'fed, and the lamps may be lighted, all in the manner well known. \Vhen unvaporized particles clog the space 49, or collect in the tube 23,.the said tube may be unscrewed and the parts readily cleaned. Should the wrappings 38011 the tube 35, for any reason, become clogged, the. whole tube and wrappings may be readily. removed and a new tube substituted. When hydro-carbons heavier than kerosene are to be used, it is only necessaryto wind the layers 38 on the tube 35 somewhat more-e loosely than when kerosene is to be used. In all cases, the heat from the mantles 33 serves to initially vaporize the hydro-carbon in the layers 38, and to prepare the same for the complete vaporization in the tube 23;

It is obvious that those skilled in the art may vary the details of construction as well -as the arrangement of parts without departing from the spirit "of, my invention, and

therefore, I do not wish to be limited to the abovedisclosure except as maybe required by the claims;
